While most generators are noisy and powered by gasoline, that’s not the case with the [EcoFlow](https://ecoflow.com/pages/delta-pro "undefined") DELTA Pro ($3,599 per unit), a whisper-quiet battery-powered generator about the size of a beer cooler. The DELTA Pro can fully charge from a household outlet in three hours; it’s also chargeable from solar panels or electric-vehicle charging stations. With a 3,600-watt-hour capacity, it can keep household essentials running for nearly 24 hours, and multiple units can be networked together to power a whole house for days. _—Don Steinberg_ **Correction, November 10** _The original version of this story misstated the name of the invention being recognized. It is the EcoFlow DELTA Pro, not the EcoFlow DELTA._ _The original version of this story misstated the EcoFlow DELTA Pro’s capacity. It has a 3,600-watt-hour capacity, not a 3,600-watt capacity._ ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/best-inventions-2021/6113128/ecoflow-delta-pro/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/best-inventions-2021/6113128/ecoflow-delta-pro/"},"headline":"A Portable Power Plant","datePublished":"2021-11-10T11:11:16.000Z","dateModified":"2026-03-02T23:55:46.701Z","description":"","url":"https://time.com/collections/best-inventions-2021/6113128/ecoflow-delta-pro/","keywords":["list","franchise","best inventions","Best Inventions 2021"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt2d19a24b2b20663b/698a1e8db3fce38e340c87ed/best-inventions-2021-EcoFlow.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"TIME Staff","jobTitle":null,"url":"https://time.com/author/time-staff/"}],"creator":"TIME Staff","articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt2d19a24b2b20663b/698a1e8db3fce38e340c87ed/best-inventions-2021-EcoFlow.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/collections/best-inventions-2021/6113128/ecoflow-delta-pro/","name":"A Portable Power Plant"}}]}] ```
